Remote desktop to "Direct access client"

Hi 

I need to manage clients through remote desktop when the client is connected through direct access 

I have folled these to links below.

I have activated my isatap adapter with netsh interface isatap set router <NameOrIPAddress>

And made the firewall rule to allow remote desktop on the client.

But have still no access. I think it have to do with dhcp disable on my tunnel adapter ??
